Pumpkins and Halloween go together like Christmas and Santa. A typical pumpkin costume will have an orange mask that looks like a carved out pumpkin (known as a Jack O’Lantern). Alternatively, you can simply wear any orange outfit that has a Jack O'Lantern style face printed on it. You can also choose to wear a Jack Skellington costume when he is dressed as the Pumpkin King of Halloween, that costume has a pumpkin head and a scarecrow's body.
